With MOExtended tyres (run-at tyres), you can
continue to drive your vehicle even if there is a
total loss of pressure in one or more tyres. How-
ever, the tyre aected must not show any clearly
visible damage.
You can recognise MOExtended tyres by the
MOExtended marking which appears on the side
wall of the tyre.
Vehicles with tyre pressure monitoring system:
MOExtended tyres may only be used in conjunc-
tion with an activated tyre pressure monitoring
system.
If a pressure loss warning message appears in the
driver's display, proceed as follows:
R
Check the tyre for damage.
R
If driving on, observe the following notes.
Driving distance possible in emergency mode
